Question

Concern over the weather associated with El Nino has increased interest in the possibility that the climate on earth is getting warmer. The most common theory relates an increase in atmospheric levels of carbon dioxide (CO2), a greenhouse gas, to increases in temperature. A regression analysis of the mean annual CO2 concentration (in parts per milion) in the atmosphere at the top of Mauna Loa in Hawaii and the mean annual air temperature(in degrees Celsius) over both land and sea across the globe for 37 years was performed. Assume all conditions are met for simple linear regression inference. What percent of the variation in average annual air temperatures is explained by the regression analysis with annual Co2 levels over Mauna Loa as the explanatory variable?
